We divide 843741 by 51
We want to divide 843741 by 51.

On to step 1:
The number 51 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 51

Advancing to step 2:
84 divided by 51 is 1 with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 51 away from 84, we end up with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 51

Advancing to step 3:
When dividing 333 by 51, we get 6 with a remainder of 27.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 306 away from 333, we end up with 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 51

Let's proceed to step 4:
If we divide 277 by 51, we get 5 and a remainder of 22.
Write down 5 as next digit of the result. 
Result so far: 165.0
Deduct 255 from 277 and we're left with 22.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 51

Advancing to step 5:
The number 51 fits into 224 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1654.0
Subtract 204 from 224 to get 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 51

Step 6:
51 goes into 201 3 times with a remainder of 48.
The next digit of our result is 3. 
Result so far: 16543.0
If we subtract 153 from 201, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
The number 51 fits into 480 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 16543.9
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
If we divide 210 by 51, we get 4 and a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 16543.94
Subtract 204 from 210 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 16543.941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
The number 51 fits into 90 1 times, leaving a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 16543.9411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 16543.9411, and the remainder is 0.00039.
